Those modules were like little toaster ovens internally! 10000000 NE5534 opamps per module
Yeah - with the combination of 5532s, 5534s, 4558s, TL074s and the direct out VMOS transistors with a double set of boards print side out, facing each other you could slip a steak in between and make a nice grill! All the old red plastic IC bases crack with heat/age and cause noise and intermittent faults.
Edit: not to mention the lobstered electrolytics.
